    Has anyone gone through the process it take to upgrade the Nav. System in the 2014 Prius? When you buy the upgrade from the parts dept. for $180.00 then you have to take that (It is not a CD) to service and they want to charge you another $100.00 plus to install the upgrade. I am just about finished with Toyota!!!!

    that's pretty much it. if you buy the car for the nav, toyota fail. otherwise, we use the phone or a portable device. if you really want a big screen, you could use a tablet.

    You might want to check whether there is a Technical Service Bulletin that describes the exact update process for the specific nav unit in your car. Gen 3 has different update methods depending on model year (and, for the later model years, which type of nav unit; 2010-11 had only one choice).

    A 2010 or 2011 you update just by buying the map DVD and slipping it in. Doesn't need the service department for anything.

    A 2012+ with the seven inch Denso nav needs service to install the update from the USB key, but you shouldn't need to buy that key: service should already have one in their Special Service Tools cabinet, according to the TSB that lays out the process, and of course they still have it after performing the upgrade. For that model nav, the bulletin was T-SB-0133-14 when last I checked, but there might be a newer bulletin now to go with the 2016 maps.

    For the 6.1 inch Panasonic Harman-Kardon nav, I've never looked up how the update is done.

    Seems to me if you have the kind that is updated by the service department using media that they already have (and keep), you've pretty much got no way around paying the service fee, but you should have a heart-to-heart with them about why they would send you to Parts first to buy the media....

    edit: misremembered what I had read about who made the 6.1"

    What I got from the parts dept. was a pamphlet that had looked like a number key or code on it and that is what I was to take to service and they would use that along with the computer that they plug into the car. It all seems a little to much.

    A 2014 uses a USB key for the Premium HDD. I think the 6.1" Display Audio units also use a USB to update the maps.

    Toyota switched all headunits back to a single Denso unit that runs off an SD card starting in 2014 with the Corolla (and 2016 with the Prius) so I think it's back to a a simple replaceable card (like the old DVD-based units).
